Disarmament has been central to the work of the United Nations since its founding, and it is critical for building a more secure and peaceful world. But what actually is disarmament? This video introduces audiences to the ideas and concepts behind disarmament and arms control.
How does disarmament and arms control work?
This video takes a look at the processes and mechanisms behind modern disarmament and arms control, and how we work together to realise disarmament goals.
How to engage
In this video we look at how individuals can engage with disarmament, and the importance of strengthening cooperation and coordination at all levels. We also look at the need to engage with more diverse groups to bring new perspectives, expertise and ideas to the table.
